Solved My laptop keeps going to sleep

Hey guys my laptop keeps going to sleep for no reason
It started about a week ago
It goes to sleep mostly when im watching videos with "Media player classic"
And it's not due to inactivity or the settings because i checked them!
I think it started with the previous graphics driver update
I have a Windows 10 x64 on an Asus FX553ve (16gb - gtx1050ti)

It doesnt happen when i'm gaming or surfing the web
But when i start watching videos it randomly goes to sleep
In random times like after 5minutes of watching or 15 or 70...

I tried uninstalling and reinstalling mpc and updating my graphic card driver
And it didn't work
Sometimes even after closing the mpc app, it still goes to sleep in a random manner!
I wanted to check if there's any other way of solving this before i tried to reinstall my windows!

Also, when it goes to sleep while watching videos, it happens repeatedly for 4-5 times and then stops and works fine until the next burst

Actually i found out what the problem was,
The LAV decoders which should open when watching videos with mpc(k-lite) didn't open as they should! I fixed that by reinstalling the k-lite decoder and the problem was solved!
But thank you anyway for your help!
You have a great forum!!!
